In a journal-hearing, the combination with uy pillow-block having a spherical seat, of a lining having a circumferential rih provided with anges extending in opposite directions therefrom and having spherical outer surfaeos to it said seat, and a shallow groove 'i between said surfaces in line with said ril).

In witness whereof I have hereunto set my hand this 26th day of April, 1905.

l liloclr is quite wide, so that there is plentj,7 of l support ior the ball, and the bearing of the l hull in ils seat is at such points as to give an excellent resistance to end thrust. l

1n addition to relieving the expansion by l yielding when the hearing gets hot the flanges. have also a Slight elastic or spring m'tion,\\hioh tends to deaden the shocks or l vibration communicated from the shaft to l the lining, and this assists in producing an l easier-running bearing. L

In accordance with the provisions of the paient statutes I have described the principle of operation of my invention, together YVitnesses JOHN A. MGMANUS, Jr., ALEXANDER J. R. Fusco.
